“…Based on these definitions, the residual stresses should be considered as secondary stresses. According to [29], residual stresses may be determined analytically, numerically, or from experimental measurements (e.g., destructive, semi-destructive, or nondestructive methods).…”

Numerical and experimental study was conducted on fatigue crack growth (FCG) of metallic components to investigate the redistribution of mechanical residual stresses during FCG. To this end, the compact tension specimens of an aluminium alloy were used. In addition, mechanical residual stresses were introduced near the crack tip by applying compressive and tensile loads, followed by visually observing the side-surface of the specimens to estimate the crack growth length. In the numerical simulation, cyclic J-integral was used as the crack growth fracture parameter and a good agreement was observed between the numerical and experimental results. The results of the finite element method demonstrated a clear redistribution of mechanical residual stresses during FCG. After a few cycles, the residual stress field around the crack tip reached a lower magnitude value confined in a smaller zone, although this zone was stable during the remaining fatigue process. Finally, present study evaluated the effect of stress ratio, load amplitude, and initial residual stresses level on the redistribution of residual stresses. It was observed that the residual stresses are mainly released during the first steps of fatigue loading.

“…Authors such as Zhang and Wu 10 were more focused in the spring back behavior itself, doing an integrated research with analytic, numerical and experimental approaches, monitoring the spring back behavior of a small-diameter thick-walled tube. Other authors, in turn, are involved with the residual stress estimation in pipes such as Wang and Mirzaee-Sisan 11 who used an analytical model to study the effect of plasticity induced by bending-reverse bending-straightening on residual stress generation and redistribution in pipes. In relation to flexible risers, Lopes 12 did an analytical/experimental study on the residual stress distribution in partially yielded tensile armor wires, for different imposed curvature radius, and Riagusoff et al.…”

Metallic hyperstatic structures, like beams, submitted to excessive loads, do not fail completely before fully yielding in more than one cross section. Indeed, for built-in beams, three cross sections must be fully yielded before the final failure can occur. So, modeling the evolution of the cross-section residual stress distribution is an important subject that should be addressed to guarantee the stress analysis modeling correctness. This paper analyses the residual stress distribution evolution, in critical cross sections, of built-in beams during a transversal concentrated load growth, until the final failure through hinges formation. A finite element model is also presented. The results show good matches with the numerical model, used as a reference.
